President Obama’s 2012 presidential campaign today started selling “Made in the USA” t-shirts featuring images of both President Obama and the long-form birth certificate he released copies of last month.

“Wear your support for this campaign with an official Made in the USA T-shirt,” his website advertises.[2] Donate $25 or more today and we’ll send you your limited-edition shirt.

“Remember ‘fight the smears’ from the 2008 campaign?” asked campaign spokesman Ben LaBolt. “This is the mobile version of it.”

“Fight the Smears[3]” was an Obama campaign website from 2008 that attempted to refute untruths about the campaign, such as the claim that then-Sen. Obama was a Muslim[4].

Part of the reason for the shirts, a campaign official told ABC News, is that despite the president’s release last month of his long-form birth certificate, conservative fact-challenged author Jerome Corsi’s book “Where’s the Birth Certificate?: The Case that Barack Obama is not Eligible to be President” was published this week.
